resemble those of Septogloeum salicinum (Pk.) Sacc. collected at the 
same time and place. 
SepPoria sambucina Pk. The form on Lonicera is probably S. Xylo- 
stei Sacc. & Wint. Sporules 50-75 x 2/x. 
Beptoria umbelliferarum Kalchb. There is no apparent reason why 
the specimens on Gicuta and OxypoUls should have been referred to 
this species in the supplementary list except that I did not know what 
to do with them and the inclusive appearance of the specific name. 
Each host is represented by a single specimen and they do not resem¬ 
ble each other. 
TJromyces euphorbiae C. & P. This includes U. proeminens (DC.) 
Lev. on E. polygonifolia and E. Presin and U. euphorb iicola (B. & C.) 
Tranz. on E. maculata which are perhaps better considered as races. 
Puccinia momica (Pk.) Arth. Dr. Arthur informs me that theAeci- 
dium on Arabis lyrata was collected at Trempealeau, Wis., by J. M. 
Holzinger in 1890. 
Phyllosticta simillispora Ell. & Davis. What appears to be this fun¬ 
gus has been described by Saccardo under the name Leptothyrium 
tumiduliim n. sp. (Ann. Myc. 10, 3, 312.) 
These notes are to be continued in a subsequent publication. 
I have followed the Sydows in MonograpJiia Uredinearum in using 
the specific name trifolii to designate the TJromyces that occurs on 
Trifolium pratense. Kern (Phytopathology I: 1, 3 et seq .) and Arthur 
(N. A. Flora 7: 255) apply it to the form on Trifolium repens and use 
the specific name fallens for the rust on T. pratense. The proper dis¬ 
position of the form on Trifolium hybridum is not clear. Morphologi¬ 
cally it resembles the form on T. repens from which it differs in the 
absence of an aecial stage as does that on T. pratense. Liro did not 
succeed in transferring the rust from T. repens to T. hybridum by in¬ 
oculation. 
Septoria parietariae Davis (4th suppl. list of paras, fungi of Wis. p. 
871) is probably not different from $. urticae var. parietariae Sacc. 
(Syll. Fung. 16: 971) of which I was not aware when the former name 
was proposed. 
Peridermium balsameum Pk. has been shown by Fraser to be, in part 
at least, the aecial stage of Uredinopsis. Fraser also finds that Caeoma 
abietis-canadensis is connected with Melampsora on Populus grandi- 
dentata. 
The “primary uredo” (Uredo muelleri Schroet.) occurs on the hosts 
of Kuehneola uredinis (Lk.) Arth. ( E. albida (Kuehn) Magnus) in 
Wisconsin and might properly have been designated by the numeral 
M I” because of its aecial character. The same may be said of 
Phragmidium potentillae-canadensis Diet, which is placed in Kuehneola 
by Arthur.
